Abstract
A dual clutch transmission comprises a first clutch to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches. A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches is engaged to drive the backward-traveling drive train by setting a speed change manipulator at a backward-traveling position, and the other of the first and second clutches is engaged to drive a fixed one forward-traveling speed drive train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.
